Gasgoo Munich- On July 30, GAC Group and the First Affiliated Hospital of Sun Yat-sen University signed a cooperation agreement in Guangzhou focused on anti-motion sickness technology. The partnership aims to foster long-term collaboration in mechanistic research, technology transfer, and the establishment of industry standards.

On the technical front, GAC is focusing on vehicle dynamics control, smart cabins, and the engineering of multimodal human-machine interaction. The hospital, meanwhile, brings expertise in clinical medicine, vestibular physiology, and neuroscience. Together, they aim to bridge medical science and engineering to build a complete technical chain—from physiological signal modeling to full vehicle system integration.
Combating motion sickness has emerged as a priority in vehicle comfort R&D over the past two years. Because electric motors deliver instant torque and regenerative braking creates drag, EVs often trigger "visual-vestibular" conflicts—a phenomenon that makes motion sickness roughly 17% more likely in EVs than in internal combustion engine vehicles, according to industry estimates. To address this pain point, mainstream solutions are converging on three fronts: recalibrating power output curves and braking maps to smooth out acceleration and deceleration; using electromagnetic suspension or continuous damping control (CDC) to manage pitch, roll, and vertical acceleration; and leveraging cockpit domain controllers to coordinate airflow, fragrance, audio, and ambient lighting for multi-sensory intervention.
GAC has already assembled a cross-functional team of engineers specializing in chassis, powertrain, NVH, body, and climate control for its pre-research efforts. Partnering with universities like the Beijing Institute of Technology and the preparatory Guangzhou Jiaotong University, the automaker established a human factors evaluation system for motion sickness. These efforts yielded several control strategies now deployed in the Trumpchi M8 PHEV L, which features a full-sensory intelligent anti-motion sickness system designed to reduce dizziness by smoothing power delivery, optimizing braking, and utilizing dual-valve SDC electromagnetic suspension.
Despite these advancements, the industry faces a common bottleneck: a lack of unified evaluation standards and scientific verification methods. Because subjective experiences vary so widely, it is difficult to objectively compare different technical solutions or adapt them for large-scale, platform-wide use. By including "industry standard formulation" in their scope, GAC and the hospital's partnership aims to directly address this gap.
